VALVE CONSTRUCTION.

Specification of Letters Patent.

Patented Jul 11, 1916.

Application filed January 23, 1914. Serial N 0. 813,939.

To all whom it may concern:

Be it known that I, ERNEST G. Wao nn, 1 a citizen of the United States, resid ng atl Lewiston, in the county of Nez Force and State of Idaho, have invented a new and useful Valve Construction, of which I the 1 coupling element of a hose, or the like, may

following is a specification.

The present invention appertains generally to valves, and aims to provide a novel and improved valve construction, especially as over the valve construction disclosed inthe oo-pending application, filed November 12 1913, Serial No. sonnet.

t is the primary ob ect of the present invention to provide a valve construct on embodying a unique assemblage of parts, so-

that the valve may be'readily opened by force, but will be seated by the pressure of the water or other fluid alone, whereby 1t 1s.

impossible for an inexperienced person to jam the valve against its seat, means also being provided for independently actuating the valve to pulverize or eject any accumula-. tions of foreign or extraneous matter beh oasmgl is provided with an inwardly protween the valve and its seat. v

Another object of the present invention is to provide a valve construction of the nature indicated, which will be comparatively simple, substantial, durable, compact and1n-.

expensive, as well as convenient, and efficient in its use.

With the foregoing general objects outlined, and with other objects in view, which will be apparent as the nature of the invention is better understood, the present invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preclse embodiment of the invention herein disclosed can be made within the scope of'what 1s claimed without departing from the i it of the invention.

or tap 2 adjoining its open end, and with an;

opposite lateral discharge port or tap 3, into which is inserted, a collar or nipple Efihav ing a flange 3 seating against the boss around the outlet opening 3. Thus, the inlet port 2 may be threaded or engaged to a male element or nozzle, for connecting the valve construction to a hydrant, or other source of water or fluid, while the female be engaged over the collar or nipple 3 The body or casing 1 is provided intermediate the inlet and outlet ports with internal threads 4, into which is engaged a ring or annulus 5, forming a valve seat, which is preferably provided with aconical or beveled faceat that side adjacent the inlet port 2. The annulus 5 is also preferably provided with aplurality of sockets 5 adj oining' the bevel, for facilitating the application and removalof the valve seat to and from the'body or'casing, the valve seat or ring being readily removed or-inserted through the lower-or open end of the casing, which open end is normally closed by a cap or screw P i The upper or closed endof the body or jecting or depending sleeve or socket portion 7, disposed axially or concentrically within the casing or bodyl, and having a bore 8 therethrough, and opening through the upper endofthe casing. The sleeve 7 projects inwardly from the closed end of the casing to a point close adjacent the valve seat. The upper end portion of the bore 8 is counterbored or enlarged to form a stufling box 9, into-which is threaded or engaged a gland 10, to compress the packing 11 within the box 9, against a tubular or hollow stem 12 passed through the bore 8, and threadedly engaged to the lower end portion of the bore 8, as at 13. Thesorew threads between the sleeve"? and stem 12 are spaced from the stufingboxto prevent the threads from injuring the packing 11. The ,invention has been illustrated in its A stem 1% isslidable through the tubular stem 12, to be guided thereby,..and a valve or valv'e head l5 is securedlto the lower end of the stem 14 to seat upwardly against the valve seat 5, the valve being preferably conical or beveled about; its margin to snugly fit the valve seat. The lowerend ofthe tubular stem 12 projects below the sleeve 7, to cooperate'with thevalve, and the upper end of the stem 12 projects beyond the upper end of the casing, the stem 14: passing snugly through the sten1'12 to be. guided thereby.

The valve stem 14 being slidable freely through the tubular stem 12, permits the valve to be seated by the pressure of the water or fluid entering the port 2, the valve being of the check valve type. The valve 15 and stem 12 are arranged at opposite sides of the valve seat.

The upper or outer end of the stem 12 is externally threaded, as at 1'6, and has en-- threaded portion 16,- and upon-whichis engaged-the hub of'a hand wheel 20, a-jam or binding nut 21 being threaded upon the threaded portion '16'to lock or secure the hub ofthe hand-wheel-20 upon the-squared or noncircularportion19 of thestem 12. Thus, the hand wheel 20 facilitates the rotation of the stem-12, when-desired, so that'thestem may be projected downwardly or-retracted upwardly into and out ofengagement' with the valve 15, for the purposes aswill hereinfriction therein, to a 111111111111111, and 1s of after more fully appear.

Attached to the upper end of the valve stem 14, is a suitable handle or hand hold 22, which is preferably removable, in; order that under ordinary-conditions, the upper end of the stem 14 may be nonencumbered, topre vent the said stem from being rotated or drawn upwardly 'oroutwardly; Whenthe handle or lever 22 is applied-to the outer end of the valve stem 14, it enables the valve to be rotated and forced upwardly against the valve seat, topulverize or eject any accumulation between the valve and-its seat.

The present valve construction may be employed in divers'capacities, such as, for-attaching a sprinkling hose to a fire hydrant, for a blow-off for steam boilers, and the like. It is evident that when the inlet port 2 is connected with any source of fluid, the pres sure of the fluid will normally seat the valve 16, that is, when the screw or stem 12 is retracted upwardly, to permit the valve to close. To open the valve it is only necessary to run the screw or stem 12downwardly-or inwardly, whereby the tip or inner'end-ofthe operating or actuating screw or stem 12 will engage the face of the valve toforcethe valve away from-its seat and against the fluid pressure. This will enable the water or fluid to flow through'the annular valve seat and out through the-discharge port 3. "The valve, being of the check valve type, will close automatically, when the screw or-stem 12 is retracted, itbeingnotedthat the valve cannot be jammed against the valve seat through the medium of the operating stem 12, which will render it impossible to injure the valve or its seat by inexperienced persons. This is of importance, inasmuch as the jamming of the valve against the seat often results in the destruction or mutilation of the valve or'its seat, and which is of disadvantage in other respects.

Although the valve cannot be forced against its seat, through the medium of the actuating stem 12, the valve may be forced upwardly and rotated properly, through the medium of the valve stem or spindle 14, and its handle or lever 22, in order that any sedimentor accumulation betweenthe valve and its-seat'can be pulverized or ejected; The valve stem 14 being smooth and unthreaded, willslide readily through the tubular operating stem 12; whereby the valve can only be forced against the valve seat, by the upward thrust orstrain applied to the handle or lever 22. As above indicatedthe handle orlever 22 is normally removed, in order to prevent the valve from beingmanipulated through themedium of the valve stem. It is also apparent that as soon as the valve stem is released, the valve will be relieved from the pressure previously applied to the valve stem.

The" present device reduces the water advantage as over the construction disclosed in the above mentioned application, inasmuch as the operating and grinding stems12and-14, respectively, are both disposed at one end of'the casing, which enables the' valve structure to be constructed more compactly and at less expense. It is also to be noted'that both of the stuffing boxes in the present device, are located at the low pressure end of thecasing, to effectively avoid'leakage, the packing 11 preventing leakage between the operating stem 12 and the sleeve 7 and the packing -18 preventing leakage between the two stems. The valve stem or spindle 14 passingthrough the tubular operating stem '12, will be guided in an effectivemanner, in order that the valve will be constrained to slide axially in a true manner to and from the valve seat. Both of the stems being arranged at the upper end ofthe casing, makes it more convenient to operate the two stems, as above intimated.

Fr0mthe foregoing, taken in connection with the drawings, the other advantages and capabilities of the present invention will be obvious to those versed'in the art, and need not beitemized at length, it being observed that the objects aimed'at havebeen carried out satisfactorily.

Having thus described'the invention, what per end, the upper end portion of the bore of the sleeve being enlarged to form a stuffing box below the upper end of the casing, a packing within said stuffing box, a gland threaded into said stufi'ing box, a tubular stem slidable through the gland and having screw threads engaging the inner portion of the sleeve bore, the screw threads being spaced below thestufling box, and a valve 10 seatable upwardly against the valve seat and having its stem slidable freely through ture in the presence of two witnesses.
